I have done it before, just get a dremel with a reinforced cut off wheel, grinding stone and a mag with the base plate taken off. I used the baseless mag as sort of a template, traced the width of the mag on there and cut off inside the lines. Then I just ground down any excess material until the top of the mag fit. I then used the grinding wheel to grind off the tabs inside the receiver (its the only thing I had that would fit inside there) Is someone selling unconverted WASR's or is this a deal in your neck of the woods. Id love to find another cheap AK
